I don't like either of those and use #keysAndValuesDo: as it is polymorphic with other collection classes.

That said, I'd prefer #withIndexDo: [:each :index | ... ] because it preserves the #with:do: structure.

e.g.

#($a $b $c) with: (1 2 3) do: [:char :number | ... ]

Hello,

I am working on a new collection and this question caught my interest.
Between��doWithIndex: or withIndexDo:, which do you find more logical and why?
